CAN.

Application filed March 15, 1920. Serial No. 365,707.

To all whom it may concern.

Be it known that I, GEORGE A. LEIGH- ToN, a citizen of the United States, residing in Roslindale, in the county of Suffolk and State of Massacl'iusetts, have invented a new and useful Improvement in Cans, of which the following is a specification.

This invention relates in general to containers and more particularly to containers constructed with a frangible seal over the discharge opening and having external means protecting said seal prior to the opening of the can by the consumer. Cans of this character are usually constructed with a sheet of paper beneath a friction or other plug and furnished to the packer with the bottom end open for filling, a closure being later seamed in the bottom of the can by the packer. This requires that the packer be provided with apparatus for seaming the bottom of the cans into place and requires also that considerable care be exercized in the shipping and handling of the can bodies prior to the attachment of the bottoms to prevent mutilation and other damage. These bodies are not infrequently of paper and unless the ends, which are usually metal, are attached, are easily mutilated or rendered unfit for the action of the seaming apparatus.

My invention has for its principal object the construction of a can of this character which will permit of the easy attachment of the seal after the can has been filled through the discharge opening, thereby permitting attachment of the bottom by the can manufacturer and relieving the necessity for the careful packing and handling and relieving also the packer from the necessity of providing and maintaining seam- .ing equipment.

Another important object of the invention is the provision of a can of this character which may be cheaply and easily manufactured and which will permit of the provision of a filling and discharge opening of large capacity, whereby to facilitate the filling of the cans.

A further object of the invention is the provision of a can of this kind wherein the seal may be effectively protected by the use of a friction plug positioned and held above the seal.

Numerous other objects and advantages of the invention will be apparent as it is better understood from the following description, which taken in connection with the accompanying drawings discloses a preferred embodiment thereof.

()n the drawing,

Figure 1 is a perspective view of a con tainer embodying my invention;

Fig. 2 is atop plan view of this container with the friction plug removed;

Fig. 3 is a section taken substantially on the line 3-3 of Fig. 4; and

Fig. 4 is a sectional view of the top closure taken on the line et l of Fig. 2.

For the purpose of illustrating my invention I have shown on the drawing a can in which it is embodied and which comprises a rectangular fibrous body 11 to the bottom of which is seamed or crimped a sheet metal bottom or end closure 12 and to the top of which is similarly secured an end 13 having a central opening closed by a plug 14 of any usual or preferred constructlon.

My invention contemplates the provision of a frangible seal secured in place beneath the friction plug and so constructed and arranged that said seal may be fixed in location from without the container and after it has been entirely constructed and filled with material.

The end 13 is sea :d or otherwise secured as indicated at 15 to the top edge of the body 11 and is provided with a large central opening defined within a vertical or substantially cylindrical plug receiving flange 16. The material of the end 13 is bent up at 17 in dome-like form to a point 18 above the plane of the body of the end and thence down into the flange 16. At the bottom this flange is provided with a plurality of spurs or triangular projections 19 which are inserted through and held in position in a perforated disk 01 annulus 21 of cardboard or other suitable material, the purpose of this disk being to provide a shoulder 22 disposed within the opening through the flange 16. lthe friction plug, as shown on the drawing, comprises a drawn sheet metal member comprising a central body 23 surrounded by an upstanding friction wall flange 24 which terminates in an outwardly extending pry-ofi' flange 25. The spurs 19 are inserted through suitable openings in the annulus 21 and are bent back poured into the can in packing and from which it may be poured out for use. The frangible seal indicatedat 28 is a mere circular piece of paper which may carry, if desired, suitable directions upon its face, and which is secured upon the shoulder 22 by suitable adhesive and after the can has been filled. Thereafter the package may be completely closed for shipment by the insertion of the friction plug 14.

It will be manifest that when so constructed there is no necessity for the packer to provide any equipment, closing or other machines for operatlng upon the can after it has received its contents, although of course, if desired, apparatus may be provided for positioning the frangible seals. The can can be completely constructed except for the positioning of the seals by the can maker and shipped to the packer with out dan er of damage to the can.

It is t on ht that the invention and many of its atten ant advantages will be understood from the foregoing description, and it will be apparent that various changes may be made in the form, construction and arrangement of the arts without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the form hereinbefore described being merely a preferred embodiment thereof.

I claim:

1. A container com rising a body and an end secured to said ody, said end being formed with an aperture and being bent upward at a distance from said aperture and thence extending to said aperture and thence downward to provide a friction Wall, an inner perforated annulus having a horizontal part attached to the under side of said end and extending inward from said friction wall sufficiently to form a supporting shoulder, a sealing disk closing the aperture and supported on the top of said shoulder, and a friction cap seated in said aperture.

2. A container com rising a body and an end secured to said ody, said end being formed with a bent-up central dome formed with an aperture havin a depending wall the bottom edge of whic is at substantially the level of the bottom surface of said end, an inner erforated annulus attached to the under si e of said end and extending inward from said wall sufficiently to form a supporting shoulder, a sealing disk closing the aperture and supported on said shoulder, and an exterior closing cap for said aperture of the end.

3. A container comprising a body and'an end secured to said body, said end being formed with a bent-up central dome formed with an aperture having a depending wallthe bottom edge of which is at substantially the level of the bottom surface of said end, an inner erforated annulus attached to the under si e of said end and extending in ward from said Wall sufficiently to form a supporting shoulder, a sealing disk closing the aperture and supported on said shoulder, and an exterior closing cap for said aperture of the end, portions of said end being continued down from the edge of the wall of said aperture and forming spurs which pass through said annulus and are bent up on the under side of the same.

4. A container, comprising a body, an end closure therefor having a central opening, an annular shoulder-providing member located beneath said end closure against the under side of the outer part of the same and providing a shoulder within the opening through the end closure for receiving a frangible seal.

5. A container, comprising a body, an end closure therefor having a central opening, an annular shoulder-providing member separate from said end closure and located beneath said end closure and providing a shoulder within the opening through the end closure for receiving a frangible seal, saidend closure having parts interlocked with said member.

6. A container, comprising a body, an end closure therefor having a central opening, an annular shoulder-providing member separate from and located beneath said end closure and providing a shoulder within the opening through the end closure for receiV mg a fran ible seal, said closure having parts exten ing outward from the opening and interlocked with said member.

7. A container comprising a body, an annular head secured thereto, a friction wall in said head, an annulus applied to the underside of said head and having a portion protruding inward adjacent said friction wall, a friction cover fitting within said friction wall and a frangible seal between said protruding portion and said friction cover.
